- 論文の詳細を見る
Detailed dc magnetic measurements were made on the Cr. .Mn.Ge alloy systemwith 03,v30.60 in the temperature range from 4.2 K to 420 K. The alloy system isparamagnetic for 0.z,v30.06, For 0.093,v30.l5 ferromagnetism appears at low fern-peratures. The system with 0.173,v30.2l shows a dotuble transition from aparamagnetic to a ferrornagnetic state at lower temperatures and finally to a mixedphase of ferrornagnetic and spin glass ordering. For 0.243,v:j0.60 spontaneousmagnetiztion disappears and a normal spin glass phase is observed. A variety of phasetransitions observed in the present alloy system are attributed to the competition be-tween the positive contribution from modified RKKY interaction and the negativecontribution from direct exchange interaction to the Mn-Mn exchange interaction.
