“…1, [37][38][39][40][41][42][43] The opposite sign for the XMCD signals of the hysteresis loops for V and Co in Fig. 1 provide direct evidence for the opposite magnetization of the V and Co thin layers, also in agreement with published results.…”

“…On the other hand, the V magnetic moment was found to increase with increasing Co coverage and to decrease with increasing V coverage. The experimental results have been partially reproduced by recent theoretical approaches developed by Carrillo-Cázares et al 1,[38][39][40] and Jisang Hong. [41][42][43] All these theoretical results confirmed a strong polarization of the V atoms in contact with Co and the antiparallel alignment of the magnetization in V and Co layers.…”

“…1, [38][39][40][41][42][43] Note that even extremely strong saturation effects in the order of 10-20 % ͑Refs. 65 and 66͒ would not modify the observed trends in the Co and V atomic magnetic moments.…”

“…[41][42][43] All these theoretical results confirmed a strong polarization of the V atoms in contact with Co and the antiparallel alignment of the magnetization in V and Co layers. Carrillo-Cázares et al 1,[38][39][40] have performed a number of theoretical calculations in order to simulate the V / Co and Co/ V interfaces and VCo alloys and to extract the atomic magnetic moments of Co and V atoms in these systems. They found that the highest magnetic polarization of the V atoms is achieved in a VCo alloy in which the averaged V and Co magnetic moments 44 are −1.82 B and 1.56 B , respectively ͑in the first four Co layers in contact with the VCo alloy͒.…”

The magnetic and magneto-optical properties of Al/ Co/ V / MgO͑100͒ structures and the influence of the Co/ V interface for different thicknesses of the Co and V layers have been studied experimentally. From the element-specific hysteresis loops obtained by x-ray magnetic circular dichroism ͑XMCD͒ at the Co and V L 3 edges we find that the V layers are magnetically polarized antiparallel to the Co layers and that magnetization reversal occurs at the same magnetic field in both layers. The effect of the V atomic volume and the relative thicknesses of V and Co layers on the magnetic moments of the V and Co atoms are also studied. Contrary to what might be expected, the atomic magnetic moments of the V and Co atoms do not depend on the V atomic volume, however they depend strongly on the thicknesses of the V and Co layers. From the trend in the Co and V atomic magnetic moments as a function of Co and V thicknesses and the absence of any spectroscopic evidence for the formation of a VCo alloy, a long-range spin polarization of the V atoms is proposed. The extracted magneto-optical ͑MO͒ constants of V and Co as a function of photon energy clearly evidence a large amount of polarization in the V films in agreement with the XMCD results, which is indicative of the magnetic coupling between Co and V. The experimental MO results and simulations also show the strong influence of these polarized V layers in the MO properties of the complete system. These results, given the absence of spectroscopic evidence for the formation of a VCo alloy, support a long-range magnetization of the V atoms and a reduction of the Co atomic magnetic moments.

“…In addition, it was revealed through X-ray magnetic circular dichroism (XMCD) that the V atom has antiferromagnetic coupling to the Co atoms. In the theoretical view point, the interface magnetism of V films on body centered cubic (BCC) Co was reported [9], but until very recently no theoretical calculations were performed for the magnetic properties of V on FCC Co except the magnetic map of FCC at the V/Co(0 0 1) interface based on TB-LMTO calculation [15]. They considered 1, 2, and 3 ML V films on Co(0 0 1) and cð2 Â 2Þ surface alloy structure.…”
