“…The moderate conducting character and significant spin-polarization of electron hoppings, possessed by obtained model crystals, signifies the principal necessity of pairwise infinitesimal spin rotations to be employed. It is generally validated by the statement, that spin-polarized hoppings do cause intrinsic incorrespondence between single and pairwise spin rotations approaches while estimating the exchange interactions landscape [29].…”

In this work we conduct a numerical search of non-trivial mechanisms, leading to new tendencies towards long-range ferromagnetic ordering in two-dimensional materials. For this purpose we employ an original variant of pairwise infinitesimal spin rotations technique to establish the magnetic transition temperature as the rigid function of basic crystal's parameters. It favored the numerical optimization of this function using modified genetic algorithm, designed to harvest local extrema. It resulted in revealing the moderate metallicity, accompanied by essential orbital anisotropy, as the prime configuration, which provides the most favoring conditions to ferromagnetic ordering, related to double-exchange and superexchange mechanisms.

“…Already before February 2022, when compared to other Asian states, China significantly dominated the import and export partner share of Russia's trade with the region (Kapoor, 2022), as discussed in the earlier section. A key consequence of the ongoing war, with far‐reaching implications for Moscow, is expected to be an increased reliance on China (Kashin, 2022) where the relationship was already developing in an asymmetric manner. Russia has also put its relations with China at the center of implementing the GEP.…”

Wither the Greater Eurasian Partnership? Challenges from the East in an evolving world order

The idea of the Greater Eurasian Partnership (GEP) has gained increasing currency in Russian foreign policy. The Russia–China partnership has been presented as its bedrock through a partnership between the Eurasian Economic Union and the Belt and Road Initiative, further expanding to include other regional powers from across East Asia, South Asia, Central Asia, and Middle East as well as nonwestern multilateral groupings (SCO, ASEAN). Given the centrality of Asia‐Pacific to this expansive concept, GEP has to deal with the challenges posed by the evolving regional geopolitics of the East and the rise of the Indo‐Pacific amidst heightened US–China rivalry. The paper seeks to conduct a policy review of GEP and its proposed development format in light of ongoing changes in the East to determine the likely future of the concept in a contested region that also remains at the center of this expansive Russian vision.
