Co 2 MnZ（Z=Si、Ge、Sn和Ga）中的 59 Co和 55 Mn NMR频率ν通过cw方法测量为温度T和压力P的函数。随着T/TC的增加，59Co的ν/ν4.2值比55Mn下降得更快，特别是在Co2MnGa中，与其他合金的结果相比，0°C时∂ν/∂P为正值。
The59Co and55Mn NMR frequencies ν in Co2MnZ (Z = Si, Ge, Sn and Ga) were measured as a function of temperatureTand pressurePby the cw method. The ν/ν4.2value decreased faster for59Co than for55Mn with increasingT/TCespecially in Co2MnGa, for which ∂ν/∂Pwas positive at 0°C in contrast to the results in other alloys.
