Spectra of the Effects of Magnetic Birefringence and Dichroism in Magnetic Colloids with Different Particle Sizes

An experimental study is performed of the spectral dependences of effects of birefringence and dichroism in magnetic colloids with magnetite nanoparticles that have average sizes of 5.5 and 8 nm. It is shown that the magnitude of the effects in a sample with larger particles is approximately twice...
