چکیده
• Combining two different compounds made them have a mutual force that caused the creation of new properties from those either compound individually. Accordingly, nanocomposites MF/CuAl were synthesized by sol-gel in steps. Here, effect between MF and CuAl was apparent; lattice parameters are individual MF. Also, single-domain grains CoF/CuAl magnetically hard high coercivity remanent magnetization . While NiF/CuAl MgF/CuAl multidomain region domain walls present, tends to decrease. But ZnF/CuAl particles superparamagnetic with region. From hyperthermia study, NF/CuAl has maximum SAR minimum time required reach desired hyperthermic temperature as compared other samples. So can be employed magneto-hyperthermia systems. The sol gel method used make 2 O 4 (MF = CoFe , NiFe MgFe ZnFe ) All characterized using X-Ray Diffraction (XRD), Fourier Transform Infrared spectroscopy (FT-IR), High-resolution Transmission Electron Microscope (HR-TEM). results show there spinal structure phases + CuAl). particle size is suitable for biological applications. magnetic examined Vibrating Sample Magnetometer (VSM). samples showed typical ferrimagnetic behavior, except ZnF/CuAl, which found superparamagnetic. heating efficiency all investigated measuring Specific Absorption Rate (SAR) parameter. value well saturation (M s lowest (H c value. very distinctive nanocomposite applications, promising systems treatment cancer.
