Abstract
The structural, electric and magnetic properties of bulk hexagonal Lu1-xSrxFeO3 (x = 0 and 0.15) ceramics are investigated. XRD data and rietveld refinement confirm the hexagonal structure with P63cm space group. Magnetic measurements for Sr-doped sample indicate a ferromagnetic-like behavior at the room temperature with a very high coercivity of the order of ∼ 4.4 kOe. P-E hysteresis loops show an enhanced ferroelectric property with Sr doping. Hence, towards the realization of applications, the multiferroic properties of hexagonal LuFeO3 are improved remarkably by 15% Sr substitution at Lu site.
Highlights
Room temperature multiferroics are very much fascinating due to the potential applications in spintronics and memory devices
We focus on achieving room temperature (RT) magnetism in the sample by doping Sr at Lu site of the LFO
It is noticed that lattice parameters, a and c, the cell volume (V) of the hexagonal LuFeO3 decreases with Sr doping content, x = 0.15
