Y1-xEuxMn2O5 nanorod samples (x = 0, 0.5, and 1) were prepared and crystallized in an orthorhombic structure with the Pbam space group. Magnetic susceptibility experiments revealed that the size effect reduced the effective magnetic moment and interaction among magnetic moments. All six samples exhibited AFM ordering and canted AFM domain below 50 K, and adjustable by varying the size of the nanorods. Hysteresis experiments revealed the size effect induced exchange bias. Room-temperature Raman spectra revealed a red-shift in all of x = 0 and x = 1 samples in an applied magnetic field, indicating that a spin-phonon interaction existed at room temperature.
