(Color online) The AFM (left) and MFM (right) images of the HT5 sample. Below the examples of some inclusions: left AFM image, right MFM for the same inclusions. The size of the inclusions was from 100 nm up to 700 nm. Magnetic contrast is typical for magnetization along the surface plane.
(Color online) The AFM (left) and MFM (right) images of the E3 sample. Below the example of some inclusions: left AFM image, right MFM for the same inclusions. The size of the inclusions was from 100 nm up to 700 nm. Magnetic contrast is typical for magnetization normal to the surface plane.
(Color online) (a) Bright field image of cross-section of the HT-5 sample; (b) The HRTEM image of rectangular MnSb inclusion inside the GaSb matrix near surface of the HT-5 sample (electron beam is parallel to [1-2.0] direction of MnSb and  direction of GaSb); (c) zoomed part of the image (b) in frame showing detail of the “moiré” contrast; (d) SAD diffraction pattern of area marked in (b).
The scanning electron image of the D26 sample with the 100 nm inclusions.
Magnetization of HT5 sample as a function of magnetic field (a) and temperature (b).
Magnetic moment of HT5 as a function of temperature, measured according to the protocol FC and ZFC.
The magnetic hysteresis for the sample HT5 at the temperature T = 5K and T = 300K, the magnetic field was in the plane of sample surface (a), the measurements for the magnetic field aligned along and normal to the sample surface for the HT5 sample (b).
The XMCD spectra for MnSb bulk layer grown on the GaAs (111)A substrate measured at two angles. The signal is considered here as characteristic for bulk material.
The XMCD spectra measured at the angle of 30o for samples grown on GaSb(001) substrate HT5 and D26 (a) and for two areas of D26 sample (b).
The XMCD spectra for sample E27 grown on GaAs(111)A substrate. The signal was observed only at angle close to 70o (line) and quickly went down at other angles (circle). This confirms that for this sample the inclusions with easy magnetization axis oriented close to the surface normal were formed.
