Second-harmonic signal in electric-field-modulated EPR spectra of Fe3 spin triangles
Jason S. R. McCoombs, Jorge I. Hilari, Jérôme Robert +4
We present electric-field-modulated electron paramagnetic resonance (EFM-EPR) measurements on centrosymmetric single crystals of the molecular spin triangle $\mathrm{[{Fe_3}O({O_2}…

Structure and magnetism of MnGe thin films grown with a nonmagnetic CrSi template
B. D. MacNeil, J. S. R. McCoombs, D. Kalliecharan +7
We report a method to grow B20 MnGe thin films using molecular-beam epitaxy, which employs an ultrathin CrSi template layer on Si(111). This layer is expected to be nonmagnetic, in…

Giant anomalous Hall effect in epitaxial MnGe films with a cubic kagome structure
J. S. R. McCoombs, B. D. MacNeil, V. Askarpour +8
We report on the first example of epitaxial MnGe thin films with a cubic structure. The films are found to exhibit frustrated ferromagnetism with an average magnet…
