A Néel N-type ferrimagnet, SmMnO3, exhibits a striking magnetocapacitive effect around the compensation temperature. To clarify the origin of the magnetocapacitive effect, the magnetic states of the Sm 4f and the Mn 3d moments in SmMnO3 were investigated by means of X-ray magnetic circular dichroism (XMCD). The information on the Sm 4f and the Mn 3d magnetic states were obtained by using soft X-rays for the Sm M4,5 and the Mn L2,3 edges, respectively. Our soft XMCD data directly demonstrate that the magnetocapacitive effect of SmMnO3 is induced by simultaneous reversals of Sm 4f and Mn 3d angular momenta.

(a) Schematic diagram of the fabrication setup for cascaded long-period fiber gratings (LPFGs) on polarization-maintaining photonic crystal fiber (PMPCF), (b) side-view image of the fabricated grating, and (c) its polarization-dependent in-
fiber Mach-Zehnder interference spectra measured for orthogonal input polarization states denoted by polarizer angles of 0
° (red) and 90° (blue). The inset of (b) shows a cross-sectional image of the PMPCF. SIDs A and B are the two fringe dips used as sensor indicators. (d) Schematic diagram of the proposed sensor and wavelength shifts of SIDs A (red) and B (blue), measured for applied (e) strain and (f) temperature changes.
