“…The Tc for these MNPs reached room temperature when the Al +3 content was 1.5 < x < 1.8 [107]. A similar exchange of Sr +2 or Ti +4 in La 1− x Sr x Mn 1− y Ti y O 3 MNPs led to a decrease in Tc from ~90 °C to ~20 °C; the Ti +4 -substituted La 1− x Sr x Mn 1− y Ti y O 3 MNPs had higher values of Ms and sharper Tc transitions when compared to the Sr +2 -substituted La 1− x Sr x Mn 1− y Ti y O 3 MNPs [108]. Another study by Miller et al .…”

The tremendous interest in magnetic nanoparticles (MNPs) is reflected in published research that ranges from novel methods of synthesis of unique nanoparticle shapes and composite structures to a large number of MNP characterization techniques, and finally to their use in many biomedical and nanotechnology-based applications. The knowledge gained from this vast body of research can be made more useful if we organize the associated results to correlate key magnetic properties with the parameters that influence them. Tuning these properties of MNPs will allow us to tailor nanoparticles for specific applications, thus increasing their effectiveness. The complex magnetic behavior exhibited by MNPs is governed by many factors; these factors can either improve or adversely affect the desired magnetic properties. In this report, we have outlined a matrix of parameters that can be varied to tune the magnetic properties of nanoparticles. For practical utility, this review focuses on the effect of size, shape, composition, and shell-core structure on saturation magnetization, coercivity, blocking temperature, and relaxation time.

“…As it can be seen in curve a the obtained precursor have amorphous structure. In curve b, the observed diffraction peaks are corresponded to the perovskite structure of LSMTO nanoparticles [9,18]. No peak of any unreacted or impurity phase was detected in the curve b, which indicates the high purity of the obtained product.…”

“…Recently, ferromagnetic materials such as the series of La 1−x Sr x MnO 3 (LSMO) compounds with tunable T c between 10 and 90 • C for 0.18 < x < 0.6, have attracted great interest for hyperthermia application [8]. Phuc et al [9] showed that the replacement of Mn ions by titanium in La 1−x Sr x Mn 1−y Ti y O 3 have particular advantages over the variation of Sr doping level for tuning the T c of the component.…”

In this study, La 0.7 Sr 0.3 Mn 0.98 Ti 0.02 O 3 (LSMTO) nanoparticles with a perovskite structure and an average particle size of 23.5 nm were synthesized using a reverse microemulsion method. In this method, cetyltrimethylammonium bromide (CTAB) was used as a surfactant, 1-butanol as a co-surfactant, n-hexane as a continuous oil phase, and an aqueous solution containing metal cations or precipitating agent as a dispersed aqueous phase. The aqueous nanodroplets of microemulsions were used for the formation of perovskite precursor. The obtained precursor was then calcined at 700 • C for 4 h to convert the precursor to the perovskite phase. In addition, the heating ability of the LSMTO nanoparticles was evaluated under a safe alternating magnetic field used in magnetic hyperthermia therapy. The results showed the fast magneto-temperature response of the prepared sample with sufficient heat loss at the therapeutic temperature range, indicating the LSMTO nanoparticles can be used as a self-regulated heating agent in the magnetic hyperthermia therapy.
