LOW TEMPERATURE REGION MAGNETIC REFRIGERATION WORKING SUBSTANCE AND MAGNETIC REFRIGERATION SYSTEM |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a magnetic refrigeration working substance exhibiting excellent cooling capacity particularly in a low temperature region of ≤200 K, and to provide a magnetic cooling system. <P>SOLUTION: In NaZn<SB>13</SB>type La(Fe<SB>x</SB>Si<SB>1-x</SB>)<SB>13</SB>as a magnetic refrigeration working substance, Ce or/and Mn are partially substituted, and its composition is made into La<SB>1-z</SB>Ce<SB>z</SB>(Fe<SB>x</SB>Mn<SB>y</SB>Si<SB>1-x-y</SB>)<SB>13</SB>. In the magnetic refrigeration system, cooling control is performed using the above magnetic refrigeration working substance NaZn<SB>13</SB>type La<SB>1-z</SB>Ce<SB>z</SB>(Fe<SB>x</SB>Mn<SB>y</SB>Si<SB>1-x-y</SB>)<SB>13</SB>by one kind or a plurality of ones in which the above composition is changed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
