Strain-modulated helimagnetism and emergent magnetic phase diagrams in highly crystalline MnP nanorod films
We explore strain-modulated helimagnetism in highly crystalline MnP nanorod films grown on Si(100) substrates using molecular beam epitaxy. The strained MnP film exhibits a paramagnetic to ferromagnetic (FM) phase transition at T C ∼ 279 K , and the FM to helical phase transition at T N ∼ 110 K . The value of T N is greater than T N ∼ 47 K for the MnP single crystal, indicating strong strain-modulated helimagnetic states in the MnP nanorod film. The presence of significant thermal hysteresis in the helical phase indicates the coexistence of competing magnetic interactions, leading to the first-order metamagnetic transition. Similar to its single-crystal coun...
