抄録

We measured angular dependences of single-crystal magnetization for the chiral structural molecule-based metamagnet [Mn(hfac)<SUB>2</SUB>]·BNO<SUP>*</SUP> (<B>1</B>). This crystal shows remarkable crystal direction dependences of spin flip transition in all crystallographic <I>a</I>, <I>b</I>, and <I>c</I> axes and the transitions are observed at different critical magnetic fields (<I>H</I> || <I>a</I>: 640 Oe, <I>H</I> || <I>b</I>: 1000 Oe, and <I>H</I> || <I>c</I>: 1250 Oe at 2 K). These results mean that <B>1</B> has independent antiferromagnetic multi-sublattices. We calculated its possible magnetic structure from magnetic data and constructed magnetic structural model.
