在不同衬底上生长的Cr掺杂SnO_2薄膜在室温以上都表现出良好的铁磁性。令人惊讶的是，在LaAlO 3衬底上生长的Sn-0.95 Cr-0.05 O-2薄膜具有6 μ（B）/Cr的巨磁矩，这比在相同条件下在SrTiO 3和R切割蓝宝石衬底上生长的薄膜大20-30倍。所有薄膜都是高度透明的。
Laser ablated Cr-doped SnO2 thin films grown on various kinds of substrates all show ferromagnetism well, beyond room temperature. Surprisingly, films of Sn-0.95 Cr-0.05 O-2 grown on LaAlO3 substrates have, a giant magnetic moment of 6 mu(B)/Cr, which is 20-30 times larger than that of films grown under the same conditions on SrTiO3 and R-cut sapphire substrates. All films are highly transparent.
