Tuning ferromagnetism and spin state in La${}_{(1-x)}$$A_x$CoO${}_3$ ($A=$ Sr, Ca) nanoparticles

Ravi Prakash, Rishabh Shukla, Priyanka +2

We use the x-ray diffraction, magnetic susceptibility, isothermal magnetization, and photoelectron spectroscopy to study the structural, magnetic and electronic properties of La$_{…
