稀土213家族的化学通式一般写为（R,Ba）2CuO4-x,这里R表示

稀土213家族的化学通式一般写为（R,Ba）2CuO4-x,这里R表示某一种稀土元素。至少有十种稀土元素可以用来合成这个家族的超导体。这个化学分子式中含两个（R，Ba）类原子，一个Cu原子，4个氧原子，所以被称为214结构。在晶格中，R和Ba的位置是等价的，所以这里把它们看作一类原子。由于一般地讲，在晶格中存在着氧原子少缺，所以在分子式中写成O4-x。这个家族的超导转变温度约为36K。
稀土224家族的化学通式为RBa2Cu3O7-x,R同样表示某个稀土元素。至少有13种稀土元素可以用来合成这个家族的超导体。因为这个家族的分子式中金属元素的个数分别为1，2和3，所以人们把这三种家族称为123超导体家族。因为元素的增多，人们习惯上不再把氧原子写出来表示这个家族。由于这个家族被发现的第一个成员的稀土元素是钇（Y），所以人们也常把123家族称为钇家族。123家族的超导转变温度为90K左右。

213 family of rare earth chemical formula written as (R,Ba) 2CuO4-x, where r represents a rare earth element. At least ten kinds of rare-earth elements can be used to manufacture the family of superconductors. The chemical formula for two (R,Ba) class Atom, Cu Atom 4 oxygen atoms, so called 214 structure. In the lattice, r position and Ba are equivalent, so put them here as a kind of atoms. Generally speaking, there is less oxygen atom in the lattice, and so written in the molecular formula O4-x. The superconducting transition temperature of about 36K of the family.Rare earth 224 family, a rare earth elements with chemical formula for RBa2Cu3O7-x,R the same. There are at least 13 species of rare-earth elements can be used to manufacture the family of superconductors. Because the formula for the number of elements in this family are 1, 2 and 3, so people called the 123 superconductor family of three families. Because an element of increasing, people get used to no longer to represent oxygen atoms to write on the family. Because the family is found is the first member of the rare-earth element yttrium (Y), so it is also called yttrium 123 family family. 123 family of superconducting transition temperature of about 90K.

213 chemical formula of the rare earth family generally written as (R, Ba) 2CuO4-x , where R a represents a rare earth element. From at least 10 rare earth elements can be used to synthesize the family of superconductors. The chemical formula containing two (R, Ba) class atom, a Cu atom and four oxygen atoms, so called 214 structures. In the lattice, the position R and Ba are equivalent, so here sees them as a class of atoms. Because generally speaking, there is a little lack of oxygen atoms in the crystal lattice, so written O4-x in formulas. The family of the superconducting transition temperature of about 36K.
RE 224 family of chemical formula RBa2Cu3O7-x, R also represents a rare earth element. At least 13 kinds of rare earth elements can be used to synthesize the family of superconductors. Because the number of the family of metal elements in the formula 1, 2 and 3 respectively, these three families so people called 123 superconductors family. Because the increase in the elements, it is customary to no longer represent an oxygen atom to write out the family. Because REE a member of this family to be discovered yttrium (Y), so it is also often referred to as the 123 family yttrium family. 123 family of superconducting transition temperature of about 90K.

The chemical formula of rare earth 213 family general (R, Ba) written as 2CuO4-x, where R represents a rare earth element. At least ten kinds of rare earth elements can be used to synthesize the family of superconductors. This chemical formula contains two (R, Ba) atoms, one Cu atom and 4 oxygen atoms, so it is called the 214 structure. The positions of R and Ba are equivalent in the crystal lattice, so they are considered as a class of atoms. Generally speaking, there are few oxygen atoms in the lattice, so it is written in the molecular formula O4-x. The superconducting transition temperature of this family is about 36K.The chemical formula of rare earth 224 family RBa2Cu3O7-x, R also said that a rare earth element. At least 13 kinds of rare earth elements can be used to synthesize the family of superconductors. Because the number of metal elements in this family is 1, 2 and 3, the three families are called the 123 super conductor. Because of the increase in the number of elements, people are not used to write out the oxygen atoms to represent the family. Since the first member of the family was found to be the rare earth element is Y, so people also often called the 123 family of yttrium family. The superconducting transition temperature of the 123 family is about 90K.
