BaCu2(Si1-xGex)2O7 - A spin 1/2 chain material with tunable inter-chain inter...

BaCu2Ge2O7 is reported to be a one dimensional Heisenberg antiferromagnet, with three dimensional long range order at low temperatures due to small antiferromagnetic...据报道，BaCu₂Ge₂O₇属于一维海森堡反铁磁体（one-dimensional Heisenberg antiferromagnet），由于微弱的反铁磁……作用，其在低温下呈现三维长程有序（three-dimensional long range order）。
