題目:
Field Induced Gap Formation in Yb4As3
講師:
上田和夫 (東大物性研、教授)
日時・場所:
平成11年11月8日(月)15:00-
物理教室大学院講義室 2-211にて
要旨: The field-induced gap observed in specific heat of Yb_4As_3 is interpreted
as due to the effective staggered field introduced by the alternating
g-tensor and by alternating Dzyaloshinsky-Moriya interaction. This mechanism
provides also a natural explanation for the anomalous increase of magnetic
susceptibility at low temperatures. A specific prediction is made for the
dependence of the gap on the field direction.
