Abstract Scope |
In rare earth element based materials the alloyed p-block elements provide chemical formation and stability, and control magnetism exhibited by rare earths. We report here an example of how alloyed non-magnetic element pinpointed an enhanced as well as controlled magnetism, magneto-crystalline anisotropy, and phase transformation. One example is R2T (R = rare earth, T = p-block element), in which the R-5d states strongly hybridize with the T-p states exhibiting large exchange splitting in ferromagnetic configuration. This unexpectedly high exchange splitting is the root cause of the sharp para-magnetic to ferromagnetic transition [1].
