Spherical MnFe 2 O 4 and MnFe 2 O 4 @YPO 4 :5 Eu 3+ magnetic nanoparticles have been prepared by co‐precipitation method. Crystal structure, morphology, elemental composition and surface structure were characterised by X‐ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS) and Infra‐red spectroscopy (IR). Their calculated average crystallite sizes are found to be 28 and 35 nm respectively. And the prepared nanoparticles are having spherical morphology. The composite bond formation between MnFe 2 O 4 and YPO 4 :5 Eu 3+ is confirmed by more intense bending vibrations of PO 4 3− group for hybrid nanoparticles. The magnetization of hybrid nanoparticles shows magnetization per gram of MnFe 2 O 4 , M s = 34.355 emu/g with negligible coercivity indicating superparamagnetic behaviour. Prepared magnetic nanoparticles achieve hyperthermia temperature (42 °C to 47 °C) under AC magnetic field indicating potential material for biological application. The prepared nanoparticles are showing red luminescence peaks at 615 nm and 702 nm, which are included in the range of biological window.
