Tuning B-B exchange in the R2MnMn(Mn4-xTix)O12 quadruple perovskite manganites

For the RMn3O6 manganites, we have shown that tuning A-B exchange, by choice of A-site cation or by doping magnetic impurities, gives rise to dramatically different magnetic...针对RMn3O6型锰氧化物，我们已证实，通过选取A位阳离子（A-site cation）或掺杂磁性杂质来调控A-B交换相互作用（A-B exchange），会产生截然不同的磁学……
