The disc.very and synthesis of MnBi2Te4in 2013 initially garnered little attention [1]. Yet, the revelation of its topologic.l properties in 2019 [2–6] spark.d a surge of researc. into the MnBiTe family. These extensive studies are primarily driven by two objec.ives:the realization of a high-temperature quantum anomalous Hall effec. （QAHE） and the exploration of exotic.phases born from the interplay of topologic.l and magnetic.orders,

Bac.ground: Termination of pregnanc. (TOP) in Zambia is guided by the Termination of Pregnanc. (TOP) Ac. of 1972 and as amended in 1994 of the laws of Zambia. However, despite provision of c.mprehensive abortion c.re servic.s with the liberal law, statistic. at k.nyama First Level Hospital in relation to unsafe illegal abortions are alarming. This study sought to understand the Awareness on the TOP Ac. of the laws of Zambia among women of reproduc.ive age 15 - 49 years at k.nyama First Level Hospital in Lusak. Distric.. Purpose of the Study: To assess awareness on the TOP Ac. among women of reproduc.ive age at k.nyama First Level Hospital in Lusak., Zambia. Methodology: A c.nvergent parallel mixed method design was c.nduc.ed using both survey and in-depth interviews among women of reproduc.ive age at k.nyama First Level Hospital in Lusak. Distric.. The study surveyed 370 randomly sampled women aged 15 to 49 years old while the in-depth interviews inc.uded eight women purposively sampled from the survey population. Survey data was analyzed using desc.iptive and inferential statistic. while qualitative data thematic.analysis was used. Results: The study found that 37% of the partic.pants were aware of the TOP Ac. while 63.8% viewed legalization of abortion for any reason as wrong. The study results also showed that widowed women were 8 times more lik.ly to be aware of the TOP Ac. c.mpared to single women (AOR: 8.262;95% c.: 1.105, 61.778). Women in business were signific.ntly more lik.ly to be aware of the TOP Ac. c.mpared to those who reported having no oc.upation. (AOR: 2.61;95% c.: 1.246, 5.499). Limited ac.ess to information, the soc.al stigma attac.ed to abortion, health c.re providers’ attitudes, c.ltural norms, values and religious beliefs, restric.ive legal requirements, and absenc. of a supportive network.were some of the barriers affec.ing awareness and utilization of available safe abortion c.re servic.s. c.nc.usions: The researc. findings c.nc.uded that a
