The new double perovskite Mn2MnReO6 has been synthesised at high pressure. Mn(2+) and Re(6+) spins order antiferromagnetically through two successive transitions that are coupled by magnetoelastic effects, as order of the Mn spins at 109 K leads to lattice distortions that reduce frustration prompting Re order at 99 K.
新型双钙钛矿Mn₂MnReO₆已在高压下合成。Mn²⁺和Re⁶⁺自旋通过两个连续的、由磁弹性效应耦合的转变呈反铁磁有序,因为在109 K时Mn自旋的有序导致晶格畸变,从而减少了阻碍,促使Re在99 K时有序。
