Doping lanthanum manganites particles with strontium-calcium for application in hyperthermia

The use of materials capable of controlling the threshold temperature required in hyperthermia, as well as meeting desired requirements in biomedical applications is still a challenge. In the present study, strontium doped calcium lanthanum manganites La0.7Ca0.3-xSrxMnO3 (x=0, 0.1, 0.15 and 0.2) wer...

Descrição
Resumo:The use of materials capable of controlling the threshold temperature required in hyperthermia, as well as meeting desired requirements in biomedical applications is still a challenge. In the present study, strontium doped calcium lanthanum manganites La0.7Ca0.3-xSrxMnO3 (x=0, 0.1, 0.15 and 0.2) were synthesized by co-precipitation method. Vibrating sample magnetometry (VSM) was used to study the effect of Ca-Sr ratio change on magnetic properties. The Curie temperature (Tc) increases from 272 to 315 K as the concentration increases from x=0 to x=0.2, respectively. Hence the strontium amount plays an essential role in achieving the desired Tc. X-ray diffraction (XRD) was used to identify the rhombohedral structure and scanning electronic microscopy (SEM) was used to characterize the cubic morphology and determinate the average particles size around 800 nm.
