Spin excitations in an alternating quantum spin chain

We propose to measure the magnetic excitations in malachite, a mineral that contains S=1/2 alternating chains with an alternation parameter of J'/J=0.5, just in the middle...本研究拟对孔雀石（malachite）中的磁激发（magnetic excitations）开展测量。该矿物含有自旋1/2（S=1/2）交替自旋链，其交替参数为J'/J=0.5，恰好处于中点……
