- The magnetoelastic phase transitions were observed in MnRhAs$\text{}_{1-x}$P$\text{}_{x}$ system (space group P6̅2m) by X-ray measurements (80 K < T < 300 K). For x = 0.33 and x = 0.4 contents an abrupt change of both lattice parameters and of the elementary cell volume at the metamagnetic transition was detected. The Korringa-Kohn-Rostoker electronic structure calculations performed for MnRhP compound show significant variations of densities of states at the Fermi level, while changing lattice data. The Korringa-Kohn- Rostoker-coherent potential approximation studies of disordered MnRhAs$\text{}_{1-x}$P$\text{}_{x}$ system (x=0.6, 0.8, 1.0) were done at the ferromagnetic region. From our calculations we observe moving of bands near E$\text{}_{F}$, while substituting with isoelectronic metalloid, likely as while changing the crystal data in MnRhP.
