Witryna2 sie 2024 · In addition to the irreversibility, FC magnetization also displays a slight re-entrant spin-glass behavior below 100 K, i.e., decreased magnetization as the temperature is lowered. This behavior is reminiscent of spin-glass order, which can appear even in a canonical spin-glass system. 29. login ldry.comWitryna10 cze 2012 · Kinoshita M. p-Nitrophenyl nitronyl nitroxide: The first organic ferromagnet.
